Garlic contains an active ingredient called allicin, which is good for you in a lot of ways. It has antibacterial, anti-inflammatory, and anti-fungal properties. This helps your kidneys to filter harmful invaders from your blood. Garlic is also a mild diuretic, which means that it can increase the volume of your urine and thereby eliminate excess sodium from the body.
Regular consumption of garlic has also been found to reduce the concentration of cadmium and lead in your kidneys, blood stream, heart, liver, and spleen. Get lots of healthy allicin from onions, too.
